POWERJJRIVER FOR AGRICULTURAL MPLEMENS.

Specification of Letters Patent.

Patented Jana 2l, i919;

Applicationled October 25, 1917. Serial No. 198,495.

To aZZ 'whom 'it may Concern:

Be it known. that I, Iilnnrrrunun Faun nl? Pox'r, a citizen ot the United States, residing at lvlontchanin, county oil 1New Castle, and State oi' Delaware, have invented a new and useful Improvement in Power-Drivers for rigricultural Implements, ot' which the following is a full, clear, and exact description, reference beingbr had to the 'accompanying drawings7 .which form a part of this specification.

The object of my invention is to provide a power agricultural implement which will be light in weight and combine all the advantages of a hand, implement with the use of power to the end that it may be used in small kitchen gardens as well as in larger truck gardens. y

A further object of my invent-ion is to so construct the implement as to render the power etlicient regardless et' the lack of traction ot the wheels due to lightness; also to construct the implement at a cost which place it within the-reach o't' all classes ot gardeners. v

Referring to the accompanying drawings in which I have illustrated a preferred embodiment of my invention- I..

Figure 1 is a plan view ot' my invention applied to a cultivator. v

Fig. 2 is aside elevation of the subjectmatter of Fig. 1.

Fig. 3 is a detail ot the clutch.

Fig. Ll is a detail oi the winding drum.

The frame@ is provided with the wheel Z) and handles c. Beneath the frame are de taclmbl'y Jfastened the cultivator teeth (Z. On the frame is mounted the light gasolene engine e connected with the winding drum f by a pair ot' gears g and g and the 'friction clutch ZL, one member of which is tixed to the engine shaft while the other carries the gear The winding drum is held in connection with the gear y by means ot' the sha tt i and retainingr key i; the drum is driven through the pins r, \vliicli pi'oject trom the gear g and enter holes in the flange ot the drum.

'.lo the frame at any convenient point is fastened the arm Z which carries thewinding drum f at its end` the drum being held in position by the pins m. The trame is provided as at o with means `tor fastening' the arm Z on either side of the trame.

' ing theretaining key j;

.The front end of the frame is provided with the lip p, which acts as a guide for the flexible cable n carried by the drum p. The cable a is provided with a ring or loop T at one end, which is adapted to pass over and tasten the cable to a stake s ydriven into the ground. The drum f carries the cable la provided with a ring or loop adapted to pass over and fasten the cable to a stake, as in the case ot the cable n.

rihe drums f and' f" are similar and inter. changeable and the arm Z may be readily changed from one side to the other of the frame. i

The hand lever is pivoted to one ofthe handles c and is connected to the friction clutch 71, by means of thelink c, the bell crank 'w 'fastened to the frame and the link w, which connects with the arm z on the cam y,move ment ozt which causes the clutch faces to ene gage or disengage under the action of the cams i/ and u. The clutch s engaged or disengaged by manipulation oit the hand lever Z.

In operation the implement is used, for example, in cultivating between rows of vegetables Qin the following manner: The stake 8 is driven into the ground at the opposite end ot the row from the point Where cultivation is to start, the cable la is run out and the ring i passed over the stake. A. similar stake is 'now driven at the end of the next adjoining row, nearest the start; the cable n is then fastened to this stake. The drums y and f are then Jfastened to the gear g and the arm Z respectively.

The engine is then started and the clutch is engaged by the hand lever t. The enine then causes the drum f to Wind in the cable n, thus drawing the eultivator toward the stake s. At' the same time the cable a .is unwound .trom the drum f 1When the stake S-is reached, it is drawn out and the drum f removed by witlfnlraw-I y and slipping it. ett of the shaft d; at the same time, the drum f is removed from the arm Z. rlhe cultivater is now moved to the next row along which the cable p lies and faced in the opposite direction. The stake s is driven into the ground at the end of the adjoining' row.

The drum f is now placed on the arm Z which is moved to the opposite side of the trame, and the drum 7" fastened to the gear gl; the clutch is engaged and the cable 12 woundf implements, the combination with a vehicle for carrying'the implement, of a drum on the vehicle, a cable on the drum adapted for attachment at one end to a relatively fixed support, a motor on the vehicle, a clutch operable to vconnect and disconnect the motor andthe drum, handles extending rearwardly from the vehicles, and a manually operative connection from one handle to the clutch for operating the latter.

2. In a power driver for agricultural implements, the combination with a vehicle for carrving the implement, of a drum on the vehicle, a cable on the drum extending therefrom longitudinally in one direction andl adapted for attachment to a relatively fixed support, a motor on the vehicle` means to place tliemotor in driving relation with the drum so as to wind the cable and thereby propel the vehicle toward said sup ort, and a second cable carried by the ve icle and adapted to be unwound in the travel of the vehicle and laid in a'direction parallel to the direction of extension of the first cable;

3. In a power driverA for agricultural implements, the combination with a motor, of a drum connected with and adapted to be driven by the motor, a cable on the drum adapted to extend therefrom in one longitudinal direction to a fixed support, a sec-- 0nd drum arranged out of longitudinal alinement with `the first drum, and a cable.-

on the second drum adapted to extend therefrom in the opposite longitudinal direction to a fixed support.

4. In a power driver for agricultural implements, the combination with a vehicle for carrying the implement, of exchangeable drums on the vehicle, cables on the drums extending therefrom in respectively opposite directions, a motor o n the vehicle, and a clutch o erable to connect the motor and one of the ruins, i

5. In a power driver for agricultural iinplements, the combination with a vehicle for carrying the implement, of exchangeable drums on the vehicle, cables on the drums extending therefrom in respectively opposite directions, a motor on the vehicle, a handle on the vehicle` a clutch operable to connect and disconnect the motor and one of the drums, and connections from the handle to the clutch for operating the latter.

6. In a power drivel1 for agricultural implements, the combination with a vehicle for carrying theimplement, of a motor carried by the vvehlcle7 a drum carrier, means to secure said drum carrier to the 'vehicle in either of two diiierent positions so that the carrier will project on one side or the other thereof, gearing adapted to .be driven by the motor, a clutch operable to connect and disconnect the motor from its gearing, exchangeable drums securable either to the carrier or to the gearing, and cables carried by each drum, whereby the winding of one cable by the drum will pull thelyehicle in one direction While simultaneo'u'ly the other cable will be unwound and laid in l1v direction parallel to the travel of the vehicle.

In testimony of which invention, I have hereunto set Amy hand, at Wilmington, Delaware, on this 19th day or' October, 1917.
